The ARC-1886-xNxI presents the advanced hardware RAID technology in enhanced performance of using 6 Bays M.2 NVMe and an improved enterprise data protection of using two SAS/SATA ports. The hardware RAID adapter accesses the data of NVMe disk array with a workload preset value. While the workload level stays within the preset value, the RAID adapter would constantly back up the data of NVMe disk array to the other two SAS/SATA ports hard disk arrays. This is designed in a 1.6 GHz dual-core ROC processor, DDR4-2666 memory and PCIe Gen 4.0 host/device interface and supports RAID levels 0, 1, 10, 3, 5, 6, Single Disk or JBOD.
